The SERNA Conceptual Standard for Neural Correlates of Consciousness: Definitions, Relationships, and Theoretical Integration (SCS-NCC)

The scientific study of consciousness has transitioned from philosophical speculation to empirical neurobiology, yet it remains hindered by deep-seated terminological fragmentation and conceptual overlap. Researchers frequently conflate the "neural correlates of consciousness" (NCC) with the "neural prerequisites" or "neural consequences" of conscious experience, leading to inconsistent findings across neuroimaging and electrophysiological studies. This document presents the SERNA Conceptual Standard for Neural Correlates of Consciousness (SCS44), a unified theoretical framework designed to standardize definitions and model the causal pathways of conscious awareness. SCS44 establishes 12 canonical terms (SCS44-T01 through T12) that strictly differentiate between the minimal neural mechanisms sufficient for any specific conscious percept (Content-NCC) and the mechanisms supporting the overall state of consciousness (Full-NCC). The standard introduces the Integrated Consciousness Architecture (ICA) model, which incorporates 10 testable hypotheses (SCS44-H01 through H10) and maps the bi-directional relationships between sensory processing, global workspace activation, and subjective experience. By resolving 8 documented field inconsistencies—such as the "Pre-frontal vs. Posterior" debate—SCS44 provides a rigorous foundation for cumulative science in consciousness research, facilitating cross-study comparisons and the development of robust clinical diagnostic tools for disorders of consciousness.
